摘　　要：通过多胚水稻品系APⅣ与单胚水稻品种IR36、明恢77和龙特浦B正反杂交，研究APⅣ的多卵遗传行为，表明APⅣ的多卵性状可能不是由孢子体基因型决定的，而是由雄配子体基因型决定，属配子体遗传的范畴。The inheritance of poly-eggs was investigated by crossing and reciprocally crossing APⅣ with monoembryonic ricc variety IR36, Minghui No.77 and Longtepu B, respectively. It was suggCsted thatthe production of poly-eggs is probably controlled by gametophytic gcnotypes, rather than sporophytic ones.
